Farmers are being urged to do their bit to protect farms from damaging pest plants by ensuring machinery, vehicles and equipment have been cleaned ahead of Gypsy Day.
Gypsy Day occurs in the week leading up to and immediately following June 1 each year.
It involves the mass transporting of cows and machinery around the country's roads as farm contractors relocate themselves and their stock in time for the new season.
"Farmers and contractors have an important role to play in preventing the spread of pest plants and weeds through good on farm biosecurity practices," said council biosecurity pest plants team leader Darion Embling.
"Unclean machinery is a confirmed pathway for the spread of infestations, such as velvetleaf and alligator weed, between some farms in our region. That makes machinery hygiene especially important with Gypsy Day coming up and the mass movement of stock, machines and vehicles between farms."
